FBT provides a probe at the boundary of most functions in the kernel. The boundary of a function is crossed by entering the function and by returning from the function. FBT thus provides two functions for every function in the kernel: one upon entry to the function, and one upon return from the function. These probes are named entry
and return
, respectively. The function name, and module name are specified as part of the probe. All FBT probes specify a function name and module name.
